Referring to Figures 1 to 3, the utility model discloses a circulating ecological water tank test device for water body purification, including a control electric box 1, a water tank 2 for planting and purifying plants, and a first water tank connected to two ends of the water tank 2 respectively. Water tank 3, the second water tank 4, the bottom of the first water tank 3 is not lower than the water tank 2, the lower end of the first water tank 3 is provided with a water outlet 31, and the water in the first water tank 3 flows in from the water outlet 31 through the water inlet pipe 5 In the water tank 2, the water in the water tank 2 flows into the second water tank 4 through the overflow pipe 6 connected with the overflow port 21 provided at the upper end of the water tank 2; the first water tank 3 and the second water tank 4 are connected through the connecting pipe 7 , the connecting pipeline 7 is provided with a water pump 8, the first water tank 3 is provided with a water level gauge 32, the water pump 8 and the water level gauge 32 are connected with the control electric box 1 circuit, and the control electric box 1 controls the water pump 8 according to the water level in the first water tank 3 The working state makes the water in the second water tank 4 flow back in the first water tank 3; the purification plants include the emergent plants 91 located on the wall of the tank 2, the floating plants 92 floating on the water surface in the tank 2 and the water plants located at the bottom of the tank 2 With the submerged plants 93, the water in the first water tank 3 circulates and flows through the purification plants for purification.

Wherein, the first water tank 3 can be fixed on the fixed frame 12 or on other devices, so that the bottom of the first water tank 3 is not lower than the top of the water tank 2, so that a height difference can be generated between the first water tank 3 and the liquid surface of the water tank 2 The gravity generated by the height difference provides the power for the water body to flow, and then the water flows from the first water tank 3 into the water tank 2 . After the sewage flows into the water tank 2, the nitrogen, phosphorus and other substances in the water body are directly absorbed by the roots or leaves of the purified plants planted in the water tank 2; Various forms of nitrogen and phosphorus substances or other substances in the water body are absorbed from the roots or leaves according to the needs of plant growth and development, and the substances in the water body are transferred to the plants. Through the transformation of microorganisms in the water and the replacement of plants and Harvesting, taking away the substances absorbed by plants in the water body, so as to achieve the purpose of purifying the water body.

Because there is a height difference between the first water tank 3 and the water tank 2, the water in the first water tank 3 will flow into the water tank 2 under the gravity generated by the height difference; during this process, when the water level in the water tank 2 reaches the overflow port 21 When, similarly, because there is the height difference of liquid level between water tank 2 and the second water tank 4, the water in the water tank 2 also can flow in the second water tank 4 under the gravity that height difference produces; When the water level of the water in the first water tank 3 is lower than the preset water level range, the control electric box 1 controls the water pump 8 to draw water from the second water tank 4 into the first water tank 3; when the water level is higher than the preset water level range, the control electric box 1. Control the water pump 8 to stop operation; maintain the flow rate of the water outlet at the lower end of the first water tank 3 through the height difference between the first water tank 3 and the water tank 2 to form a continuous circulation loop. During the process of circulation, the water body can be continuously purified by the purification plants in the water tank 2. When the purified water body meets the discharge requirements, it will be discharged outside to complete the sewage purification treatment process.

Further, the angle between the bottom of the tank 2 and the tank walls on both sides of the tank 2 is 100°-110°, so that the cross section of the tank 2 forms an inverted trapezoid, as shown in the figure, which can increase the water volume in the tank 2 The surface area is large, and the three-dimensional arrangement of plants in the water tank 2 is easy to increase the number of plants placed in the water tank 2 . Since the tank walls on both sides of the water tank 2 and the bottom of the water tank 2 form an inverted trapezoid, which is more conducive to the flow of the water body, when the water in the first water tank 3 enters the water tank 2, the water body can increase the dissolved oxygen content in the water body in a disturbed state, It is beneficial to the transformation of substances by microorganisms in the tank and the absorption of nitrogen and phosphorus substances or other substances by purification plants. Wherein, the angle between the tank wall of the tank 2 and the bottom of the tank 2 is preferably 104°, which not only avoids excessive pressure from the water body on the tank wall of the tank 2, but also achieves the purpose of increasing the surface area of the water body in the tank 2 and increasing the number of plants placed . When the angle between the wall of the water tank 2 and the bottom of the water tank 2 is 104°, the purification efficiency is relatively high.

Further, the tank wall of the water tank 2 is provided with a plurality of first fixing devices 23 for fixing the emergent plants 91, such as fixing stickers, etc., to prevent the emergent plants 91 from flowing with the flow of the water body, and then cause the emergent plants 91 to get together and not It is beneficial to the absorption of nitrogen and phosphorus substances or other substances by the emergent plants 91; the bottom of the water tank 2 is provided with a second fixing device 24 for fixing the submerged plants 93, such as a fixing ring, which also prevents the submerged plants 93 from following the water body.
